I am using an older version of Context, but running texexec on your
example gets me the correct output.

a ÷ b

Thanks Jason. You are right, it works well with MKII. The problem
seems to be with MKIV.

What about

\setuppapersize[letter][letter]
\starttext
$  a ÷ b $
\stoptext

math-def.mkiv contains

\definemathcommand [div]     [limop] {\mfunction{div}}

which overrides the definition of \div from char-def.lua. The same line is 
also present in mkii, but gets overwritten by the correct definition due 
to different order in which files are loaded.

Hans: \div should be mapped to divided sign, so I suggest that we remove 
the corresponding \definemathcommand lines from math-def.mkiv and 
math-tex.mkii (see the attached patch).
